Definitions
- the invention relates to the rotary spinning electrode of an elongated shape for the device for production of nanofibres through electrostatic spinning of polymer solutions comprising a pair of end faces, between them there are positioned spinning members formed by wire, which are distributed equally along the circumference and parallel with axis of rotation of rotary spinning electrode.
- So far known devices for production of nanofibres from polymer solution through electrostatic spinning which contain a pivoted spinning electrode of an oblong shape, are for example disclosed in WO 2005/024101 A1.
- the device comprises the spinning electrode in the shape of a cylinder, which rotates around its main axis and by a lower section of the surface it is soaked into the polymer solution.
- Polymer solution is by a surface of the cylinder carried out into the electric field between the spinning and collecting electrode, where the nanofibres are created, which are carried away towards the collecting electrode and before it they deposit on a substrate material.
- This device is very good capable to produce nanofibres from water polymer solutions, nevertheless the layer of nanofibres applied on the substrate material is not uniformly spread along the whole length of spinning electrode.
- Such spinning electrode is able to carry out a sufficient quantity of polymer solution to the most suitable places of electric field between the spinning and collecting electrode, and at the same time to to spin also the non-water solutions of polymers and to produce a uniform layer of nanofibres. Nevertheless, a demanding production of such spinning electrode, and consequently also its price represents the disadvantage.
- DE 101 36 255 B4 discloses a device for production of fibres from polymer solution or polymer melt comprising at least two spinning electrode mechanisms, each of them is formed by a system of parallel wires mounted on a pair of continuous belts embraced around two guiding cylinders, which are positioned one above another, while the lower guiding cylinder extends into the polymer solution or molten polymer. Between these two spinning electrode mechanisms the textile is passed as an counter electrode, while the spinning electrode mechanisms simultaneously create coating both on face side and backside of the textile.
- the spinning electrode is connected to a source of high voltage together with counter electrode, which is formed by an electrically conductive circulating belt.
- Polymer solution or polymer melt are carried out by means of wires into electric field between the spinning electrode and counter electrode, where are from the polymer solution or polymer melt produced fibres, which are carried to counter electrode and impinge on textile positioned on counter electrode.
- a long time of staying of polymer solution or polymer melt in electric field represents a disadvantage, because the polymer solution as well as the polymer melt are subject to ageing quite quickly, and during the spinning process it changes its properties, which results also in changes of parameters of produced fibres, especially of their diameter.
- the goal of the invention is to create a simple and reliable spinning electrode for a device for production of nanofibres from polymer solution through electrostatic spinning in the electric field created between the collecting electrode and spinning electrode.
- the principle of invention is achieved by a rotary spinning electrode for the device for production of nanofibres through electrostatic spinning of polymer solutions containing a pair of end faces, between them there are positioned spinning members formed by wire, which are distributed equally along the circumference of end faces, while the principle of the invention consists in that the end faces are made of electrically non-conducting material and all spinning members are mutually connected in a electrically conductive manner.
- the spinning electrode created in this manner is able to spin water as well as non- water polymer solution and along its whole length it reaches a highly uniform spinning effect, while electric field for spinning is created between the individual spinning members after they step off the polymer solution and subsequently approach to the collecting electrode.
- the spinning members are divided into pairs, out of which each is formed by one metal cord and these cords are crossed on end faces.
- Similar effect may be also achieved by removing the electrically conductive shaft from a space between the end faces, and through mounting of each of the end faces to an independent hinge, that is coupled with the drive of spinning electrode.
- the rotary spinning electrode is schematically shown in enclosed drawings, where the Fig. 1 shows axonometric view of electrode according to the invention, the Fig. 2 axonometric view of electrode in embodiment with spinning members formed by one cord crossing on end faces , the Fig. 3 a view to electrode in embodiment with spinning members divided into pairs, out of which each is formed by one cord crossing on end faces , and the Fig. 4 shows mounting of the spinning electrode in alternative embodiment without shaft in reservoir of polymer solution.

From the groove 23 the cord 5 runs parallel with the axis 41 of a shaft 4 into the opposite groove 33 on circumference of the end face 3, while the section of the cord 5 between the grooves 23 and 33 creates another spinning element of the spinning electrode 1.
- the cord 5 passes further through the following radial grooves 34, 35 and 36 on circumference of the end face 3 and through the following radial grooves 24, 25 and 26 on circumference of the end face 2, while the sections of the cord 5 between the end faces 2 and 3 parallel with axis 4J. create individual spinning elements of the spinning electrode 1, while the sections of the cord 5 run on outer sides of the end faces 2 and 3 interconnect the spinning elements in a conductive manner.
- the cord 5 may be in radial grooves on circumference of the end face 2 and the end face 3 mounted in several further different manners, out of which one is shown in the Fig. 2.
- the cord 5 is, same as in the previous example, enclosed into endless loop, while in this case thanks to manner of its mounting in radial grooves on circumference of the end face 2 and on circumference of the end face 3 the cord 5 is crossed on outer sides of the end faces 2 and 3.
- the cord 5 passes parallel with the axis 4J. of the shaft 4, into the opposite groove 3_1 on circumference of the end face 3, while the section of the cord 5 between the grooves 21. and 3J. form one of the spinning elements of the spinning electrode ⁇ .
- the cord 5 passes to the outer side of the end face 3, reversed from the end face 2, through which it runs into the groove 34 performed in an opposite section of circumference of the end face 3.
- the cord 5 After passing the groove 34 the cord 5 runs parallel with the axis 41 of the shaft 4 into the opposite groove 24 on circumference of the end face 2, while the section of the cord 5 between the grooves 34 and 24 forms another spinning element of the spinning electrode 1.
- the cord 5 is brought to outer side of the end face 2, on which it runs to the groove 26 performed in an opposite section of circumference of the end face 2.
- the cord 5 is parallel with the axis 41 of the shaft 4 brought into the opposite groove 36 on circumference of the end face 3, and between the grooves 26 and 36 it forms another spinning element of the spinning electrode ⁇ _.
- the cord 5 is further brought to the outer side of the end face 3, on which it runs to the groove 33 performed in an opposite section of circumference of the end face 3, while on the end face 3 the cord 5 is crossed.
- the cord 5 from the groove 33 further runs parallel with the axis 41 of the shaft 4 into the opposite groove 23 on circumference of the end face 2, whereby the section of the cord 5 between the grooves 33 and 23 forms another spinning element of the spinning electrode V
- the cord 5 passes to the outer side of the end face 2, on which it further runs into the groove 25 performed in an opposite section of circumference of the end face 2, while on the outer side of the end face 2 the cord 5 is crossed.
- the cord 5 After passing the groove 25 the cord 5 runs parallel with axis 4J- of the shaft 4 into opposite groove 35 on circumference of the end face 3, and its section between the grooves 25 and 35 creates another spinning element.
- the cord 5 By means of the groove 35 the cord 5 is brought to the outer side of the end face 3, on which it runs into the groove 32 performed in opposite section of circumference of the end face 3, so that on the end face 3 the cord 5 is crossed again.
- the cord further runs parallel with the axis 41 of the shaft 4 into the opposite groove 22 on circumference of the end face 2, whereby it forms another spinning element of the spinning electrode 1 , .
- the cord 5 Through the groove 22 the cord 5 is brought onto outer side of the end face 2, on which it is brought into the groove 21..
- FIG. 1 and Fig. 2 may differ especially by mounting the cord 5 in radial grooves on circumference of the end faces 2 and 3, while the cord 5 is always endless, made of one piece and its ends are connected on one of the end faces 2, 3.
- the cord 5 in a device for production of nanofibres is through a known manner connected with one pole of the not represented source of high voltage, possibly it is grounded, so that on all spinning elements of the spinning electrode there is the same voltage.
- Example of embodiment of the spinning electrode 1, which is from the point of view of maintenance and possible replacement of the damaged or defective spinning elements the most suitable is represented on the Fig. 3.
- the spinning electrode 1 is made in the same way as in the previous embodiments according to the Fig. 1 and 2 with the only difference, that the endless loop from the cord 5 is in the represented example of embodiment formed by three independent endless loops 514, 525 and 536, which cross mutually each other on the end faces.
- the cord 514 comes out from the radial groove 2J. on circumference of the end face 2, and parallel with the axis 4J. of the shaft 4 enters into the opposite groove 31. on circumference of the end face 3 and its section between the grooves 7 ⁇ _ and 3J. forms one of the spinning elements of the spinning electrode ⁇ _.
- the cord 514 is brought to outer side of the end face 3, on which it runs into the groove 34 in opposite section of circumference of the end face 3, through which passes parallel with axis 4J. of the shaft 4 into the opposite groove 24 on circumference of the end face 2, and so creates between the grooves 34 and 24 another spinning element of the spinning electrode 1.
- the cord 514 is brought to outer side of the end face 2 on which it runs into the neighbouring groove 21..
- the cord 514 and/or cord 525 and/or cord 536 is then in dependence on production technology of nanofibres connected in a known manner with one pole of the not represented source of high voltage, possibly it is grounded.
- the shaft 4 in the space between the end faces 2 and 3 is superseded by a spacing tube of electrically non-conducting material.
- the spacing tube then considerably contributes not only to screening of electric fields of opposite spinning elements of the spinning electrode ⁇ , thus to stabilisation of the spinning process, but also to higher stiffness of the spinning electrode ⁇ _.
- the shaft 4, possibly the spacing tube of the spinning electrode ⁇ is in the device for production of nanofibres horizontally and rotatably mounted in the not represented reservoir of polymer solution, while some of the spinning elements on a lower side of the spinning electrode 1 reversed from the collecting electrode are plunged into the polymer solution contained in reservoir of polymer solution, while in a case when the shaft 4 is superseded by a spacing tube, there is no undesired contact between the spacing tube and polymer solution.
- the shaft 4, possibly the spacing tube or other part of the spinning electrode is further in a known manner coupled with not represented drive for rotation motion of the spinning electrode ⁇ .
- the spinning electrode 1 thanks to the drive rotates around its longitudinal axis and its spinning elements positioned uniformly along the circumference of the end faces 2 and 3 are subsequently plunged under the level of polymer solution in the reservoir of polymer solution and thanks to its physical properties they emerge above the level covered by the polymer solution.
- the spinning element with polymer solution subsequently approaches to the collecting electrode, which is in dependence on the technology of electrostatic spinning grounded or connected to the opposite pole of high voltage source than the spinning elements of the spinning electrode V
- the spinning element approaches sufficiently to the collecting electrode, between it and the collecting electrode as a result of difference of their electric potentials there is created a sufficiently strong electric field, which along the whole length of the spinning element initiates the spinning process.
- the polymer nanofibres are created from the polymer solution on surface of the spinning element, which through the action of force of electrostatic field move towards the collecting electrode.
- the spinning element remains in a position suitable for spinning of the polymer solution on its surface only for a certain time interval, whose length is adequate to the speed of rotation of the spinning electrode 1 around axis 41., and after expiry of this time interval it is moved away from vicinity of the collecting electrode and consequently again plunged into the polymer solution in the reservoir of polymer solution. Into the vicinity of the collecting electrode meanwhile subsequently get further spinning elements containing the polymer solution for spinning on their surface.
- the spinning electrode with described arrangement of the spinning elements thus enables a continuous production of nanofibres.
- the construction of the spinning electrode 1 nevertheless is not restricted only to the above described examples of embodiment and their modifications.
- the spinning electrode 1 in this case comprises two end faces 2 and 3, out of which each is formed by a disk from electrically non conducting material.
- the end faces 2 and 3 on the outer side are provided with hinges 20 and
- the hinges are provided with tooth wheels 201, 301 and in the mounting their mutual axial position is secured by some of the known manner, in the represented example of embodiment by means of the distance rings 202, 302 mounted in necks in the hinges 20 and 30 and abuting against the outer wall of the reservoir 6 of polymer solution.
- the tooth wheels 201_, 30J. are coupled with driving tooth wheels 82, 83, which are coupled with the drive 8.
- connection of tooth wheels 201., 30_l and driving tooth wheels 82, 83 serves not only for a drive of the end faces 2 and 3 in the same direction and with the same speed, but also to ensure the constant mutual position of the end faces 2 and 3, in which the corresponding grooves in both end faces 2 and 3 are arranged against each other, so that through these grooves passing spinning means is parallel with rotation axis of the end faces 2 and 3.
- radial grooves 21., 22, 23, 24, 25 and 26 and around the whole circumference of the end face 3 there are evenly positioned radial grooves 3J., 32. 33.
- spinning electrode 1_ On basis of all of the above mentioned examples of embodiments nearly unlimited quantity of various more or less different variants of spinning electrode 1_ may be created, which vary from the described examples of embodiment especially by a number of radial grooves on circumference of the end faces 2 and 3, thus by a number of spinning elements of the spinning electrode 1., possibly through that the cord 5 or cords 5 are not enclosed into the endless loop, but that they begin and finish on an outer side of some of the end faces 2, 3. Further differences may be attained also through a various embodiments of the end faces 2 and 3, which may be created in principle as any three dimensional body.
- the most convenient solution of the end faces 2 and 3 nevertheless seems to be the disk of electrically non-conducting material, whose edges are rounded with respect to the durability and safeness of the cord 5 or cords 5, and to minimisation of effect of these end faces 2 and 3 on the spinning process as well.
- Another possible variant of embodiment of the spinning electrode 1 according to the invention is the variant, when in the end faces 2 and 3 there are, instead of the radial grooves, performed openings, in which one or more cords 5 are positioned, Upon usage of the spinning electrode 1 of this structure nevertheless there occur difficulties caused especially by influence of polymer solution, which is into the electrostatic field between the collecting and spinning electrode 1 carried on surfaces of the end faces 2 and 3. The danger of initiation of spinning process on the end faces is prevented by suitable wiping means of polymer solution allocated to the end faces.
- the spinning electrode according to the invention is applicable in a device for production of nanofibres through electrostatic spinning of water as well as non-water polymer solutions.
